SPARK-ARRESTER.

SPECIFICATION forming part of Letters Patent No. 234,349, dated November9, 1880.

Application filed M31011 9, 1880. (No rnodeL) Fig. 2 is part Fig. 3 is asmoke to prevent the escape of the former from the mouth of the stack.

A is the outer casing of the body or stem B. O is the saddle, which isattached, as usual, to the locomotive. The body B extends up through thelower part of the flaring collar D in an extension, B.

F is the deflector. This is of conical form and ends at top in agoose-neck or curved pipe, G, which receives the sparks and conveys themdownward to the annular cinder-chamberH between the body and the case.The pipe G may, if preferred, lead to some other placefor instance, becontinued downward and discharge the cinders upon the track, asindicated in dotted lines in Fig. 1.

The pipe G, instead of descending outside the cap orcasin g K, mayextend down between the deflector and the casing K. WVhere the cin dersare delivered upon the ground or to other place than to the chamber Hthe case A may be dispensed with.

I is an orifice through the case A for the discharge of cinders from thechamber H. This orifice may be closed by a slide, 1, or otherwise. Theorifice I may have a pipe conducting the cinders and sparks to theground or any other place.

d (Z are orifices in the flaring collar D for the escape of smoke, &c.,from the cinder-chamber H.

It will be seen that the lower end of the deflector F has greaterdiameter than the top 13 of the body, so that all the heavier parts ofthe products of combustion are projected into the deflector where theyare concentrated to the discharge-orifice f and pass into the pipe G.The deflector has in its sides orifices f for the lateral escape ofsmoke and gases. The

orifices are inclined downwardly toward the outer ends, so that thecinders will not be carried through them by the force of the blast.

It will be seen that as the cinders have a rapid upward motion, and areheavy as compared with the smoke, they will pass upward to the dischargef, while the smoke will be crowded outward by the contracting form ofthe deflector, and having but little momentum will escape laterallythrough the downwardly-inclined orifices f. specific gravity, will someof it escape laterally before reaching the deflector, and will passupward through the orifices f in the flange F of the deflector, and willhave free egress through the mouth or upper end, J, of the casing oropen cap K. The course of the smoke is shown by single-headed arrows andthat of the cinders by double-headed arrows.

I claim as my invention- 1. In a spark-arrester, the conical deflectorF, with openingsfif, and f substantially as shown and described.

2. The combination of upright open-bottomcd conical deflector having anopening, f, at the apex and side openings, f, and the conducting-pipeGr, substantially as set forth.

3. The body B, with extension B and flaring collar D, in combinationwith the deflector, when the parts are constructed and relativelyarranged substantially as set forth.

4. The combinationof body B, conical deflector having its face downward,and with side openings for escape of smoke, and pipe leading from theapex of the deflector to the chiller-chamber H, or otherwise.

5.The conical deflector F, when provided with orifice fand with inclinedorificesf, in combination with conducting-pipe G,for the purpose setforth.

6. In a spark-arrester, the deflector F in the form of an upright cone,having orificef at, the apex and side orifices, f, downwardly inclinedfrom the interior, as and for the purpose set forth.
